Specification of Letters Patent.

Patented July 20, 1915.

Application filed February 12, 1914. Serial No. 818,256.

To all whom it may concern:

Be it known that I, CHARLES M. BOWMAN, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Knockdown MetallicShipping or Storage Receptacles; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to metallic shipping and storage receptacles, hasespecial reference to that class of receptacles known to the trade asknockdown, has for its object a cheap, and durable receptacle which canbe used repeatedly for shipping or storage purposes, and the inventionconsists in certain improvements in construction, which will be fullydisclosed in the following specification and claim.

In the accompanying drawings, which form part of this specification:Figure 1 is a side elevation of a metallic shipping or storagereceptacle, set up and ready for shipping or storage purposes. Fig. 2'is an end view of the body of the receptacle, partly expanded and incondition for nesting purposes for shipment. Fig. 3 is a side elevationof one end of the receptacle in the same condition shown in Fig. 2. Fig.4 is an end view with the top of the closure removed. Fig. 5 is anenlarged detail in section, illustrating the manner of securing theclosure to the body of the receptacle, and Fig. 6 is a transversesection on line 6-6 Fig. 3. 1

Reference being had to the drawings and the designating charactersthereon, the numeral 1 indicates the body of a metallic shipping orstorage receptacle, preferably made of corrugated sheet metal, providedat its upper and lower ends with interlocking straps 2, 3, formedintegral with the body 1, which enter openings or slots 4, in the endsof the body, are bent at 5, over the projections or members 6, formedintegral with the body 1, are pressed down and form a lock joint.

To the upper and lower ends of the receptacle are additional lockingstraps 7, which may be formed integral with the body 1, or may be madeof separate pieces of material secured to the body 1.

The receptacle is provided with a closure 8, having openings 9 toreceive the locking straps 7 which after passing through said openings 9are bent over at 10 and through openings 11 in the rim 12 of the closure8 and are then turned over the edge of the bead 13 on the rim of theclosure, thus making a double locked joint.

In making my receptacle, I first take sheet metal of a length and Widthsuitable for the size of the receptacle determined upon, and by means ofa suitable die or other implement, stamp out the locking straps 2, 3 and7 and the slots or openings 4 in the body of sheet metal. The sheetmetal is then bent into-the form of a cylinder with the adjacent edgesoverlapping each other as shown in Fig. 6 with the corrugationsintermeshing. when the locking straps 2, 3 are inserted in slots oropenings 4 and bent back upon the members 6, thus forming a perfectjoint, capable of resisting internal pressure and which may besubsequently unfolded, the longitudinal joint of the receptaclereleased, if desired and a number of receptacles nested and returned forsubsequent use. The free edge of the outside overlapping member of theside joint of the body of the receptacle engages the inner ends of thestraps 2, 3, and forms a seat for the same and thereby regulates theextent of the overlapping joint.

Having thus fully described my invention, what I claim is:

A metallic shipping or storage receptacle comprising a body, endclosures for the body having flanges snugly fitting the outer contour ofthe same, radial flanges formed at right angles to said first mentionedflanges, and straps for securing said closures to said body, one end ofsaid straps being secured to the inner wall of said body, the other endof said straps being passed through openings formed in said closures,trained over the outer wall of the closures and over the outer wall ofsaid first men.- tioned flanges, passed downwardly through openingsformed in said radial flanges im- In testimony whereof I aflix mysignamediagely adjacent the juncture thereof with ture, in presence oftwo Witnesses.

said rst mentioned flanges trained outwardly under said radial flaiigesand bent 7 CHARLES M up and over the edges thereof and into lock-Witnesses:

ing engagement with the upperface of said CHAS; H. BENI R;

radial flanges. SPENCER EVANS.
